General Information:

Author: IISD, IUCN, Helvetas, SEI

Year of publication: 2012

Available languages: English French Spanish

Details of Assessment:

Type of assessment: Comprehensive impact and risk assessment

Format of assessment: Web tool

Details: Desktop application that runs on Microsoft Windows 7 or newer versions

Estimated costs for conducting: Costs associated with the project team meetings and community consultations

Estimated duration of assessment: Between two and five days

To be carried out by whom: Multiple actors

Details: CRiSTAL targets project planners and managers working at the local or community level. However, a wide range of other actors may also use the tool (including policy-makers and decision makers).

Institutional scale of use: Local/community

Details: CRiSTAL targets project planners and managers working at the local or community level

Assesment to be used by which target audience: Others (please specify)

Details: Project managers of local development projects

Output: Report

Details: List of livelihood resources that are most affected by climate hazards and most important for responding to climate impacts; Proposed adjustments to existing projects and new activities to support climate adaptation; List of desired adaptation outcomes and important influencing factors to be monitored.


Coverage & Methodology:

Region of origin: North America, Europe

Developed by which sector: Science, Development cooperation

Applied in practice: Yes

Geographic coverage in analysis: Worldwide

Potential geographic coverage: Worldwide

Sectors covered: Livelihood sector

Details: Basic unit of assessment are resources needed for livelihoods - no sectoral specification

Method used: Mixed method approach

Description of methodology: Information collected from desk-based review and stakeholder consultations at the local level (community and other local experts) using participatory methods. Includes impact chains

Risk framework used: AR5

Risk components incorporated: All

Hazards and impacts considered in the assessment: All hazards

Source of required data: Primary and secondary

Details: Ongoing project activities; current and future climate conditions; information on livelihoods and groups; ecosystem and environmental degradation

Temporal scale: Current, Forward looking

Participatory elements: Yes

Details: Emphasis is put on stakeholder consultations and mapping of resources / climate risks by local focus group

Consideration of interconnectedness and -dependencies of risks: Partly

Adressing uncertainty: Yes

Details: We therefore recommend that you compare different sources and look for projections that are based on different models and scenarios. Also, make sure to note any uncertainty ranges that are mentioned in the projections (e.g., a projected 3°C temperature rise by 2050 may come with an uncertainty range of 1.5°C to 5°C; average rainfall projections may be negative but the uncertainty range can be from +20% to -50%; extreme events projections are often even more uncertain)

Scope of assessment: Identification of risks, assessment of impacts, identification of adaptation options, priorization of adaptation options, identification of limits to adaptation

Details: Consultation are supposed to analyse whether current response strategies are sustainable and will continue to be so in future

Relevance for losses and damages:

Economic/Non-Economic losses incorporated: Economic

Applicability for entire risk spectrum (from extreme weather events to slow onset processes): Yes

Details: Questions are formulated to address extreme events and slow onset changes in rainfall and temperature patterns


Recommendations for Adaptation measures included in Climate Risk Assessment: Yes

Details: CRiSTAL helps users to identify livelihood resources most important to climate adaptation and uses these as a basis for designing adaptation strategies

Usefulness for political purposes: Rather for individual project scale

Open access: Yes
